To treat acute and chronic liver diseases such as hepatitis, cirrhosis, liver cancer, etc., we must examine the symptoms in detail, distinguish between heat and cold, deficiency and reality, and seek the root cause of the disease to get to the heart of the matter. We should be good at grasping the characteristics of different diseases and different stages of evidence and the evolution of the law to solve the main contradiction. When there is no evidence to identify, you can start from the evolution of the disease mechanism and the physical characteristics of the patient, combined with the tongue, pulse, carefully deduced, to establish the treatment rules and methods. For example, acute hepatitis is often dominated by evil, the short duration of the disease, the right qi is not deficient, treatment should focus on removing evil, “urgent is the treatment of the symptoms” is also called, damp heat is the main contradiction, clearing damp heat is the main treatment, because the evil is not deficient, unless the patient is weak, generally do not need to overemphasize the support of the right qi; and chronic hepatitis, cirrhosis, liver cancer and other diseases Chronic hepatitis, liver cirrhosis, liver cancer and other diseases have a long course, recurrent attacks, delayed and not difficult to heal, the positive qi is injured, many internal organs dysfunction, the inability to dispel evil out, so should focus on supporting the positive qi, or “slow to treat the root”, or “both the symptoms and the root”, always to ” To avoid overemphasis on eliminating the evil, the use of violent drugs and damage to the positive energy. The establishment of treatment should be targeted, chronic liver disease is often complex pathogenesis, the original deficiency and the symptoms are real, the deficiency and the real are seen together, there are a lot of headaches, often make doctors feel at a loss to start, when establishing the treatment, must grasp the main contradiction, highlight the key points, distinguish the sequence and priority, but also pay attention to the correlation between different treatments. For example, in patients with cirrhotic ascites, the duration of the disease is long, the disease is deep, the original deficiency involves deficiency of liver, spleen, kidney qi, blood, yin and yang, and the standard reality may include qi stagnation, phlegm, damp heat, blood stasis, water drink, epidemic poison, and the same patient may have both liver and kidney yin deficiency, liver depression, spleen deficiency, spleen and kidney yang deficiency, blood stasis, water-damp flooding, damp-heat accumulation and other symptoms, each with its own severity, the identification should grasp the main contradiction, such as ascites is obvious, abdominal distension is the main, can be The treatment should be established to dredge the liver and strengthen the spleen, promote water retention and reduce swelling, taking into account tonifying liver yin, resolving blood stasis, and clearing heat and dampness. There is a correlation between spleen deficiency and dampness and heat. Strengthening the spleen can resolve dampness, and when dampness is removed, heat is not attached. After the ascites is reduced or subsided, the focus of treatment will be shifted to activating blood circulation and softening hardness, anti-liver fibrosis and reversing liver cirrhosis. In this way, the identification of evidence is accurate, the treatment is properly chosen, and the prescription medication may be precise.
